I'd rather go 4-3. That's not a viable 3-4 line in my opinion. If the guy coming in hasn't run the 3-4 much then they should stay 4-3. The 3-4 is not some magic formation that automatically makes things better. You need the right players to make it work. The Bills aren't there yet.
OT's are not easy to come by. That's why Philly was happy to give up a lot of crap for Peters. Once a team gets an outstanding OT they rarely let them go. JMO
Yeah, I seem to recall that too.
